CITI Talk: “On combining Networking with Computing and Research with Innovation”, Pascale Vicat-Blanc (INRIA-Agora) on December 12th at 2pm


On combining Networking with Computing and Research with Innovation


Integrating virtualised network, caching and computing into one system is becoming a natural trend to support very demanding emerging mobile applications.
I have been exploring and contributing to these ideas since many years in the context of high-performance computing (HPC), DataGrids, Cloud infrastructures, Software as a service and the Internet of Things. In this talk, I propose to articulate the researches and developments I had the chance to conduct on this topic in academic, start-up and industrial environments, and to summarise the lessons learned from these experiences. I will then briefly present my new perspectives in the field of augmented intelligence for analysing and optimising fog systems integrating tightly networking and computing.

Seminar of Carles Antón-Haro (Telecommunications Technological Center of Catalonia) on September 27th at 9.30am

The next CITI seminar will take place on September 27th, at 9.30am in the margin of Yuqi PhD defense. This seminar entitled “Machine- and Deep-Learning for Beam Selection in Hybrid Analog Beamforming Architectures” will be presented by Carles Antón-Haro from Telecommunications Technological Center of Catalonia.

Titre : Machine- and Deep-Learning for Beam Selection in Hybrid Analog Beamforming Architectures

Abstract : This talk deals with the application of deep learning (DL) and machine learning (ML) techniques to beam selection problems in the uplink of a mmWave communication system. Specifically, we consider a hybrid beamforming architecture comprising an analog beamforming (ABF) network followed by a zero-forcing baseband processing block. The goal is to select the optimal configuration for the ABF network based on the estimated AoAs of the various user equipments. To that aim, we consider (i) two supervised machine-learning approaches: k-nearest neighbors (kNN) and support vector classifiers (SVC); and (ii) a feed-forward deep neural network: the multilayer perceptron (MLP). Computer simulations reveal that, for a well-designed codebook of analog beamformers, this task can be effectively accomplished by such data-driven schemes. Performance, in terms of sum-rate, is very close to that achievable via exhaustive search, in particular for the MLP.

CITI Talk: “Source coding under massive random access: theory and applications”, Aline Roumy (INRIA Rennes), Wednesday, September 12th at 11am in TD-C

TITLE: Source coding under massive random access: theory and applications.

Date – 12/09/18,11h-12h, TD-C.

In this presentation we will introduce a novel source coding problem allowing massive random access to large databases. Indeed, we consider a database that is so large that, to be stored on a single server, the data have to be compressed efficiently, meaning that the redundancy/correlation between the data have to be exploited. The dataset is then stored on a server and made available to users that maywant to access only a subset of the data. Such a request for a subset of the data is indeed random, since the choice of the subset is user-dependent. Finally, massive requests are made, meaning that, upon request, the server can only perform low complexity operations (such as bit extraction but no decompression/compression).
After describing the problem, information theoretical bounds of the source coding problem will be derived. Then two applications will be presented: Free-viewpoint Television (FTV) and massive requests to a database collecting data from a large-scale sensor network (such as Smart Cities).

Aline Roumy received the Engineering degree from Ecole Nationale Superieure de l’Electronique et de ses Applications (ENSEA), France in 1996, the Master degree in 1997 and the Ph.D. degree in 2000 from the University of Cergy-Pontoise, France.

She is currently leading a project entitled Interactive Communication (InterCom) on Massive random access to subsets of compressed correlated data, and supported by the French Cominlabs excellence laboratory.

CITI Talk: “IF Neuron: theoretical study and application to digital communication”, Anne Savard (Associate Professor, IMT Lille), July 9th, at 10:30 am in TD-D room


IF Neuron: theoretical study and application to digital communication


In the context of digital communication, one main mechanism proposed in the literature to overcome the large consumption of MAC layers when establishing communications is called wake-up radio: The main processor is only waking up when receiving a specific signal, as for instance the node ID in the network. Unfortunately, since most of the wake-up receivers rely on standard micro-controller, they suffer a large decrease of energy efficiency. Nevertheless, if the wake-up receivers was designed with neuromorphic circuits, one could achieve high energy efficiency for IoT and ad hoc networks.

The main question that is tackled in this presentation is whether a neuro-inspired detection scheme using an Integrate-and-Fire neuron is reliable enough when one needs to detect a weak signal surrounded by noise.


Anne Savard received the Eng. degree in Electrical Engineering with specialization in Multimedia Systems from the Ecole Nationale Supérieure de l’Electronique et de ses Applications (ENSEA), Cergy-Pontoise, France, and the M.Sc. degree in Intelligent and Communicating Systems from Univeristé Cergy-Pontoise, both in 2012.

From October 2012to September 2015,she was a PhD student at ETIS Laboratory/ENSEA, under the supervision of Claudio Weidmann and David Declercq. Her research interests include modern channel coding, cooperative communication and multi-user information theory.

She defended her PhD entitled ‘Coding for cooperative communications: Topics in distributed source coding and relay channels’ on September, 22th, 2015.

CITI Talk: “Eye Tracking Algorithms”, Prof Radu Gabriel Bozomitu (“Gheorghe Asachi” Technical University, Romania), June 12th, at 11 am in “salle TD-C” ( Claude Chappe Building)


Eye Tracking Algorithms


In recent years, the interest in eye detection applications has increased considerably. There are a lot of eye detection methods used in different applications such as neuroscience, psychology, assistive technologies, in order to communicate with disabled patients, computer gaming, monitoring technologies for driver’s fatigue (in commercial and public transport), advertising industry, people identification based on face recognition and eye (iris) detection and in different military applications to help pilots to aim weapons just by looking at a target. A head-mounted eye tracking interface consists of an infrared video camera mounted on a frame glasses right underneath the eye, connected to a PC (or laptop), for eye pupil image acquisition and processing. This device is used to measure the point of gaze or the motion of an eye relative to the head. The presentation will focus on the software component used in eye tracking interfaces for real-time applications, which includes the algorithms for eye image binarization, pupil center detection, system calibration, mapping and ideogram selections. Different types of pupil detection algorithms are comparatively presented: the least squares fitting of ellipse, the RANdom SAmple Consensus (RANSAC) paradigm, the circular/elliptical Hough transform- based approaches, the projection method algorithm, the detection of the maximum dark area centroid in the eye image and the STARBURST algorithm.
